Electrokinetic techniques have a wide range of applications in droplet, particle, and fluid manipulation systems. In general, they can be categorized into different subgroups including electroosmosis, electrothermal, electrophoresis, dielectrophoresis, etc. The AC electrothermal (ACET) technique has been shown to be very effective in applications which involve high conductivity fluids, such as blood, which are typically used in biomedical applications. In the past few years, the ACET effect has received considerable attention. Unlike AC electroosmosis (ACEO), the ACET effect shows plateaus in force in a wide frequency range. In other words, with electrothermal force, velocity is more steady and predictable at different frequencies, compared to ACEO and dielectrophoresis (DEP). Although electrothermal microflows form as a result of Joule heating in the fluid, due to high conduction of heat to the ambience, the temperature rise in the fluid is not so high as to threaten the nature of the biofluids. The average temperature rise resulting from the ACET effect is below 5 K. In order to generate high strength AC electric fields, microfabricated electrode arrays are commonly used in microchannels. For pumping applications, it is essential to create asymmetry in the electric field, typically by having asymmetrical electrode pairs. There is no defined border between many electrokinetic techniques, and as such the point where electrothermal processes interferes with other electrokinetic techniques is not clear in the literature. In addition, there have been comprehensive reviews on micropumps, electrokinetics, and their subcategories, but the literature lacks a detailed up-to-date review on electrothermal microdevices. In this paper, a brief review is made specifically on electric fields in ACET devices, in order to provide an insight for the reader about the importance of this aspect of ACET devices and the improvements made to date.
Understanding the instantaneous response of flows to applied AC electric fields may help understand some unsolved issues in induced-charge electrokinetics and enhance performance of microfluidic devices. Since currently available velocimeters have difficulty in measuring velocity fluctuations with frequency higher than 1 kHz, most experimental studies so far focus only on the average velocity measurement in AC electrokinetic flows. Here, we present measurements of AC electroosmotic flow (AC-EOF) response time in microchannels by a novel velocimeter with submicrometer spatial resolution and microsecond temporal resolution, i.e. laser-induced fluorescence photobleaching anemometer (LIFPA). Several parameters affecting the AC-EOF response time to the applied electric signal were investigated, i.e. channel length, transverse position and solution conductivity. The experimental results show that the EOF response time under a pulsed electric field decreases with the reduction of the microchannel length, distance between the detection position to the wall and the conductivity of the solution. This work could provide a new powerful tool to measure AC electrokinetics and enhance our understanding of AC electrokinetic flows.
to understand how health service professionals involved in the care of users in psychic distress perceive the organization of the Psychosocial Care Network (RAPS - Rede de Atenção Psicossocial) in the western region of the city of São Paulo. qualitative approach study conducted with 123 professionals with higher education who work in the care points of the network. A semi-structured interview was performed and data were submitted to the Alceste program for lexical analysis. the network is in process of alignment with the mental health policy and the psychosocial rehabilitation strategy. However, the weaknesses in the work process of teams are related to deficits in human resources, structure, and communication, and to the limited appropriation of their guidelines. there are intense efforts of workers to weave the network, and barriers need to be overcome to support successful actions in mental health care in the territory. compreender como profissionais de serviços de saúde envolvidos no cuidado dos usuários em sofrimento psíquico percebem a organização da Rede de Atenção Psicossocial (RAPS) da região Oeste do Município de São Paulo. abordagem qualitativa realizada com 123 profissionais de nível superior que atuam nos pontos de atenção da rede. Realizou-se entrevista semiestruturada e os dados foram submetidos ao programa Alceste com aplicação de análise lexical. A rede está em processo de alinhamento com a política de saúde mental e estratégia de reabilitação psicossocial. No entanto, há fragilidades no processo de trabalho das equipes relacionadas ao déficit de recursos humanos, estruturais, de comunicação, e à apropriação limitada sobre suas diretrizes. Compreendeu-se que há intensidade de esforços dos trabalhadores para tecer a rede e que é necessário superar barreiras para fomentar ações exitosas no cuidado em saúde mental no território.
To identify and analyze the significant networks of family, social and hospital support described by the family caregivers of hospitalized children 5-12 years during the hospital stay. Descriptive study, exploratory and qualitative study conducted with 20 caregivers of children hospitalized in a hospital in a city in southern Brazil, through semi-structured interviews and significant social networks maps, tailored to the hospital setting. Data analysis showed that the most active social network was comprised of families through emotional support, material aid and services. Relations with hospital health care team and the hospital context were cited as providing support to the caregivers of the hospitalized child. The identification of social networks in the child's hospitalization course enables equip professionals working in the institution aiming at better targeting of actions and care for the family and hospitalized children. Identificar e analisar as redes significativas de suporte familiar, social e hospitalar descritas pelos familiares acompanhantes de crianças hospitalizadas de 5 a 12 anos, durante o período de internação. Estudo descritivo, exploratório e de cunho qualitativo realizado com 20 acompanhantes de crianças hospitalizadas em uma unidade hospitalar em uma cidade do Sul do Brasil, por meio de entrevistas semiestruturadas e dos Mapas de Redes sociais significativas, adaptado para o contexto hospitalar. A análise dos dados demonstrou que a rede social mais atuante foi composta por familiares, através de apoio emocional, ajuda material e de serviços. As relações com a equipe de saúde do hospital e com o contexto hospitalar foram citadas como capazes de fornecer apoio ao acompanhante da criança internada. a identificação das redes sociais no curso da hospitalização da criança possibilita instrumentalizar os profissionais que atuam na instituição objetivando um melhor direcionamento de ações e cuidados destinados à família e a 153554b96e
